The AlchemySOC family is based on an Alchemy-proprietary MIPS32 core. The models are called Au1000, Au1100, Au1500, Au1550, Au1200 series, and Au1300 series.

Alchemy Semiconductor was acquired by AMD in 2002, which in Summer 2006 sold the Alchemy processor line to Raza Microelectronics, Inc. In December 2007, Raza Microelectronics changed its name to RMI, Inc. In June 2009, NetLogic Microsystems acquired RMI for $183.4 million in stock.
In September 2011, Broadcom acquired all NetLogic shares in a transaction valued around $3.7bn.

UART

By default the YAMON bootloader only enables the UARTs it is using, two at max. For Au1100/1550 only UART0 and UART3 are enabled, leaving UART1 non-functional. You can simply edit the reset source file named arch/init/reset_<name of your platform>.c to enable it. Check for the uart_enable register (Offset=0x0100 from the base address) in the databook. After you've enabled it, the Linux kernel serial driver is able to detect it.
